Abstract :
Hydrocarbon (gas) explosions and fire are the hazardous events that present the greatest potential risk for offshore installations. More refined computations of the consequences of explosions and fire within the framework of quantified risk assessment and management for offshore installations are therefore required. Although the action characteristics of such hazardous events must be identified prior to an analysis of their consequences, the objective of the present paper is to develop a modeling technique for computational fluid dynamics (CFD) simulations of hydrocarbon explosions and fire. The results of this study form part of phase I of the three-phase Joint Industry Project on Explosion and Fire Engineering in floating production, storage and offloading systems (FPSO) (abbreviated by EFEF JIP).
